General Anesthesia Exposure In Infancy Causes Long-Term Memory Deficits

First time accepted submitter LordFlower (606949) writes "In a study, published today in Neuropsycopharmacology, exposure to general anesthesia in both human and rat infants was associated with long-term episodic memory deficits. Children aged 6 to 11 years exposed to general anesthesia during infancy had poorer episodic memory than age/gender matched controls. This deficit was replicated in rats using an analogous paradigm with full experimental control of pre-existing conditions could be exercised, suggesting a causal relation rather than correlational one. Prior research in rats suggests a mechanism of disrupted developmental synaptogenesis and apoptosis.

While a growing literature has demonstrated the presence of memory deficits and neurodegeneration in rats after general anesthesia exposure in infancy, this is the first to demonstrate a long-term deficit after exposure during human infancy. Given that each year 1.5 million infants undergo a surgery requiring general anesthesia, these findings are particularly alarming."

I never felt right after tonsillectomy

This is just an anecdote, not science. But that was the only time I had a general at age 5. That procedure was very common in those days. I never felt as good a muscular coordination aftwards as before. I am used to it after all these decades.
